App. G, p. 108 (1890), and 'Ibis,' 1891, p. 30], from the 

 Musgrave Range, 7000-9000 ft., and the mountains of 

 South-eastern New Guinea, by having the back and upper- 

 parts greyish-black, almost uniform in colour with the crown ; 

 in the latter form these parts are dark grey and in marked 

 contrast with the blackish crown. The grey on the sides of 

 the breast and belly is also a little darker in the present 

 species than in R. a. amncularis. 



R. concinna De Yis [Ann. Rep. New Guinea, July 1890 

 to June 1891, App. CC, p. 94 (1892)] from Mt. Suckling 

 appears to be synonymous with R. a. auricularis. 



R. a. lorentzi van Oort from the Hellwig Mountains is no 

 doubt synonymous with the true R. albolimbata, the male of 

 which appears to be distinctly larger than the female. 



Two males : wing 80*5 and 81 mm. ; tail 77 and 83 mm. 



Two females (?) : wing 70 and 72*5 mm. ; tail 70 and 72 mm. 



Younger birds are easily recognised by having scarcely 

 any whitish-buff on the middle of the breast, the feathers 

 of the rump tipped with chestnut, and the secondary quills 

 tipped with pale rufous buff. 



The species is new to the British Museum.
